This tank model was built totally stock except for the addition of weld seams all over the vehicle.  The welds were each made with an X-acto knife heated with a candle, and pressed into the plastic.  Needless to say I spent considerable time getting them all in there!  I also turned a new gun barrel from steel on a lathe.  Making a taper for such a small item was a first for me.  During the weathering process, I added mud along the tracks and lower hull as practice for my later models.
